Horn RU108003108TN35 Grooving Insert TN35 Carbide

Product Description

The HORN RU108003108TN35 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Built to the U108 series specification, this insert delivers a 0.031 inch cutting width with a 0.008 inch corner radius, making it suited for narrow grooving work where dimensional accuracy matters. It is a right-hand cutting insert secured by a screw-type holding method, ensuring rigid clamping during interrupted or continuous grooving passes. The TN35 grade designation indicates the manufacturer-specified carbide grade engineered for broad material compatibility across multiple workpiece categories.

This insert is intended for use in the HORN U108 series toolholding system. The Universal workpiece material classification covers ISO material groups K, M, N, P, and S, meaning it is applicable across cast iron, stainless steels, non-ferrous materials, carbon and alloy steels, and heat-resistant superalloys. It is commonly installed in production turning environments where consistent groove dimensions are required across high-volume runs. Machinists and CNC operators working with precision components, hydraulic fittings, shaft grooves, or sealing ring recesses will find this insert relevant to those applications.

Key Features

Compatibility

Designed for use with HORN U108 series toolholders. Compatible workpiece materials span ISO groups K, M, N, P, and S as specified by the manufacturer for this insert grade and geometry.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key as specified by the toolholder manufacturer to secure the clamping screw - do not overtighten or use impact tools. Verify insert seating and orientation against the toolholder pocket before resuming cutting operations.
